[vtkusers] vtkImageWriter issue...

[Hal Canary]

I still think you have to choose a class at some point.  You can keep
the pointer as a vtkImageWriter pointer and use polymorphism:

vtkSmartPointer<vtkImageWriter> writer;
switch (file_type)
{
case JPEG:
  writer = vtkSmartPointer<vtkJPEGWriter>::New();
  break;
case PNG:
  writer = vtkSmartPointer<vtkPNGWriter>::New();
  break;
default:
  writer = vtkSmartPointer<vtkTIFFWriter>::New();
}
writer->SetInput(vtkVolume);
writer->SetFileName(filename);
writer->Write();
